Privacy Policy

Motion AI · Version 1.1 · Last updated: July 26, 2026

Motion AI is operated by Arkn LLC ("we," "our," "us"). Arkn LLC respects your privacy. This Privacy Policy explains how we collect, use, and protect your personal information when you use our mobile application.

01Information we collect

Information you provide

• Account information: email address, name, password.
• Profile information: age, weight, height, gender, activity level.
• Activity data: activities you log, duration, intensity, calories burned.
• Goals: weekly calorie-burn targets you set.

Voice & microphone data

• Voice input: when you use voice input, your microphone audio is transcribed on-device using Apple's Speech Recognition framework.
• Audio handling: only the resulting text transcript is sent to Mistral AI for activity classification; the audio itself is never transmitted or stored.
• No audio storage: we do not record, store, or share your voice audio.

Apple Health data (optional)

If you choose to connect Apple Health, Motion AI reads workout data from it. This is entirely optional, off by default, and you can turn it off at any time in the Health app under Sharing → Apps.

• What we read: workouts, including distance, elevation climbed, active energy burned, and flights climbed.
• Why: to fill in your activity details automatically and make calorie estimates more accurate.
• Read-only: Motion AI never writes to Apple Health and cannot modify or delete anything in it.
• On-device: Health data is used to pre-fill your activity details. Only the activity you choose to save is stored on our servers.
• Not shared: Health data is never sent to Mistral AI, never used for advertising, and never shared with or sold to anyone.

Automatically collected information

• Usage data: how you interact with the app, features you use.
• Device information: device type, operating system version.
• Log data: crash reports, error logs.

02How we use your information

We use your information to:

• Provide and improve the Motion AI service.
• Calculate personalized calorie-burn estimates.
• Track your progress toward fitness goals.
• Send you notifications about your activities.
• Respond to your support requests.
• Improve app features and user experience.

03Third-party services

Mistral AI (activity classification)

We use Mistral AI to help classify and process activity descriptions you enter. When you describe an activity, this text is sent to Mistral AI's servers for processing.

What we send to Mistral AI:

• Your activity descriptions (text only).
• No personal information, names, or identifying details.

What we don't send:

• Email address, name, or account information.
• Location data.
• Health metrics or historical data.

Mistral AI does not store your input after processing. Responses are used only to classify your activity.

Supabase (database & authentication)

We use Supabase to securely store your account and activity data. All data is encrypted at rest and in transit. This includes:

• Your account credentials (encrypted).
• Profile information.
• Activity logs and goals.
• App preferences.

RevenueCat (subscription management)

If you purchase a subscription, RevenueCat processes your payment information via Apple. No credit card information is handled by us directly.

We do not sell your personal information to anyone. We only share data with:

• Mistral AI (activity descriptions for classification).
• Supabase (to store your data securely).
• RevenueCat (to manage subscriptions).
• Apple (for app distribution and payments).

Apple Health data is not in that list, and never will be. It is never shared with Mistral AI, never used for advertising or marketing, and never disclosed to any third party.

• Access your data: export your activity logs.
